Experimental investigation of the added mass of the cantilever beam partially submerged in water
The phenomena of added (virtual) mass of submerged structures are analyzed numerically and experimentally in this paper. The classical concept of modal added mass is analyzed in parallel with local added mass that is evaluated using pseudo-residual force vector. A finite element structure model is used to determine the local added mass. The model update and the model reduction techniques are necessary, and their respective roles are described and applied in determining the local added mass. The procedure is implemented to the cantilever beam partially submerged into water. Experimental modal analysis is performed on a cantilever beam in the air and on the same beam partially submerged in the water. This results in two sets of modal parameters, and the cause of their differences is presented and explained by the added mass. The results obtained this way can be used as benchmark for further study and comparison with other simulations.
